Providing x ¿¿ y that returns x if x is null otherwise y

[suugbut]

With my proposed operator, for example ¿¿ (think of it as a reversed version of ??), I can rewrite

bool? isNut = fruit?.Equals(Fruits.Nut); // <===== the simplest so far
bool? isNut = fruit is null ? null : fruit == Fruits.Nut; 

as

bool? isNut = fruit ¿¿ fruit == Fruits.Nut;

where

Fruits? fruit = null;
enum Fruits
{
    Nut,
    Kiwi,
    Lemon,
    Banana
}

Note: alt+168 can be used to easily type ¿.

If you don't like due to x ¿¿ y syntax, please consider my other syntaxes x ?> y and x ?< y at #7855 (comment).

This appears to have been suggested before (#7855)

On a more serious note, C# currently does not make use of ¿ or any non-7-bit-ASCII character in its syntax, and I highly doubt the lang team would ever want to introduce a syntax which makes use of such a character. ¿ is difficult if not impossible for a lot of people to type manually on their keyboards, which would make it excessively arduous to use this proposed operator, either having to reach for an obscure key combination (which will be different on everyone's keyboard), or having to paste the character from an external source, neither of which is ideal. I do appreciate ¿¿ for use with this operator in theory though, as it's very evidently the inverse of ??.

x ?? y
x ¿¿ y
x ⸮⸮ y

x ?? y => null
x ¿¿ y => llnu
x ⸮⸮ y => llun

• x ?< y equals to x is null ? y : x equals to x ?? y
• x ?> y equals to x is null ? x : y
